Rihanna has never really had front-loaded singles. That's why most of her #1s are able to spend multiple weeks at #1. Just look at We Found Love, Diamonds, and The Monster, her past 3 #1s.
Probably when the album version passes it on iTunes.
Since there's the:
Work (feat. Drake) - Single [Explicit]
Work (feat. Drake) - Single [Clean]
Work from ANTI (Deluxe) [Explicit]
Work from ANTI (Deluxe) [Clean]
Work from ANTI [Explicit]
Work from ANTI [Clean]
Got it.
So is that why the single version has been getting so many red updates and the album version has been stable?
